I have looked again at this and I actually couldn't find a 'to_xml' method for Array or for anything else in Ruby. The method exists in Rails, though but for ActiveRecord instances, though, not for arrays. If what you are trying to do is converting a model instance to xml and backthis is how you could do: # Converting to XML my_model_instance = MyModel.find my_id xml = my_model_instance.to_xml # Generating instance from XML my_new_model = MyModel.new my_new_model.from_xml xml -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
